COMSOL 6.2 - CornerRefinement

CornerRefinement

Decrease element size at sharp corners.

Syntax

model.component(<ctag>).mesh(<tag>).create(<ftag>,"CornerRefinement");

model.component(<ctag>).mesh(<tag>).feature(<ftag>).selection();

model.component(<ctag>).vmesh(<tag>).feature(<ftag>).selection(property);

model.component(<ctag>).mesh(<tag>).feature(<ftag>).set(property,<value>);

model.component(<ctag>).mesh(<tag>).feature(<ftag>).getType(property);

model.component(<ctag>).mesh(<tag>).feature(<ftag>).create(<ftag1>,"CornerRefinement");

model.component(<ctag>).mesh(<tag>).feature(<ftag>).feature(<ftag1>).selection();

model.component(<ctag>).mesh(<tag>).feature(<ftag>).feature(<ftag1>).selection(property);

model.component(<ctag>).mesh(<tag>).feature(<ftag>).feature(<ftag1>).
set(property,<value>);

model.component(<ctag>).mesh(<tag>).feature(<ftag>).feature(<ftag1>).getType(property);

Description

Use model.component(<ctag>).mesh(<tag>).create(<ftag>,"CornerRefinement") to decrease the element size defined in the sequence at vertices in 2D and edges in 3D that define a sharp corner. Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).create(<ftag1>,"CornerRefinement") to decrease the element size for the feature <ftag> that can be any of the types Edge, FreeQuad, FreeTri, or FreeTet.

Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).selection() or model.component(<ctag>).mesh(<tag>).feature(<ftag>).feature(<ftag1>).selection() to specify the domain selection. If you do not specify any selection, the feature is defined on the entire geometry.

Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).selection("corner").set() to specify a selection of corners to include or exclude from the automatic selection of corners.

The following properties are available:

Table 4-25: Valid Properties.
Name	Value	Default	Description
boundary	Selection		Boundary selection.
corner	Selection		Corners to include or exclude.
filter	include \| exclude		Exclude or include only selected corners.
minangle	double	240 [deg]	Minimum angle between two boundaries (sharp corner) for decreasing the element size.
refinement	double	0.25 in 2D, 0.35 in 3D	Factor multiplying the element size at sharp corners. The valid range is [0 1].
usefilter	on \| off	off	Filter implicitly defined corners.
